Step 1
Drop in any document
A lease, contract, medical bill, IRS notice, or job offer — as a PDF, a photo from your phone, or pasted text. Main AI reads scanned pages and messy formatting too, so there's nothing to clean up first, and no account needed to start.
✓No sign-up required to read your first document

Step 2
Every clause gets read
Main AI reads the way a careful lawyer would — every clause, every footnote, every cross-reference. It never skims. The dense, boring paragraphs most people scroll past are exactly where it slows down, because that's where the traps are buried.
✓Catches what's hidden in definitions and cross-references

Step 3
Risks flagged, law cited
Every clause is scored from Critical to Clear, and each flag is tied to the specific law it breaks — like NY Real Property Law §235-f on a four-hour entry notice. You see what's wrong, how serious it is, and the statute that proves it.

Step 4
Then you act
Don't just find out you got a bad deal — fix it. Main AI drafts the redline to send back, lays the old terms against the new ones side by side, and lets you e-sign the moment the contract is actually fair. Reading is only where it starts.

NY Real Property Law §235-f requires 24-hour minimum notice. This lease tried to make it 4. One landlord, three violations in one document.

Clear
The verdict: NY Real Property Law §235-f requires 24-hour minimum entry notice. This lease tried to make it four. That clause is unenforceable — and there are two more like it.
Most tools stop at "here's what's wrong." Main AI helps you do something about it — draft the redline, compare versions, and sign when it's right.
Negotiate — AI drafts the counter for you

Sign & monitor
Built-in e-signature closes the loop, and ongoing monitoring re-checks tracked contracts when terms or laws shift, so a clean document today doesn't quietly turn against you later.
Main AI is built on a zero-knowledge architecture. Your files are encrypted with a key only you hold — even our own servers can't decrypt your leases, contracts, or medical records.
